PHONOGRAPH.

Application filed January 2, 1925. Serial No. 129.

To all whom t may concern.'

Be it known that I, DONALD THOMAS AL- LEN, a citizen of the UnitedStates, and resident of Milwaukee, in the county ot Mil- 5 waukee andState of Wisconsin, have invented certain 4new and useful Improvementsin Phonographs; and I do hereby declare that the following is a full,clear, and exact description thereof.

This invention relates to phonographs'.

Objects of this invention are to provide a portable phonograph which maybe folded into a compact formation, which is provided with a horn ofample size having a relatively large mouth or outlet portion, and toprovide a phonograph which is so constructed that a slide carried by thecover closes the outer end of the horn and protects such horn againstentrance of dirt or other harmful material.

Further objects are to provide a portable phonograph which is otextremely simple construction, which may be cheaply produced, and whichis effective in operation.

An embodiment ot' the invention is shown in the accompanying drawings,in which Figure 1 is a vertical sectional view through the phonographshowing it in closed position, such view corresponding to a section onthe line 1-1 ot Figure 2.

Figure 2 is a front view partly broken away showing the phonograph open.

The phonograph is substantially of box like construction and comprises abase member 1 having a rear wall 2, side walls 3 and a front wall 4. Atop 5 is provided and may be of substantially the same general contouras the bottom portion. This top has downwardly extending marginalportions 6, the rear ot which is hinged to the rear wall 2 of the bottomportion.

The bottom is provided with a horizontal partition 7 upon which the tonearm 8 is swivelly mounted in the usual manner. Any suitable type ofphonograph motor is mounted in the bottom and drives the record-carryingdisk 18, as may be .seen from Figure 2. The tone arm opens into the baseportion adjacent a rear corner thereof. A curving wall 17 is positionedvertically between the partition 7 and the bottom wall 2 of the bottomhalt ot the device and extends to the front wall 4. The vertill Wall, itwill be noted from Figure 2, forms with the opposed side wall 3 agradually increasing space which constitutes a horn.

It is to be particularly noted from Figure 4 that the front wall 4 iscut out to provide an elongated opening 9 forming the mouth of the horn.A curved deflector plate 10 (see Figure 1) is positioned immediatelybelow the outlet portion of the tone arm 8 and may be secured either atits upper or its lower end or in fact at both to the bottom half ot thedevice.

It is to be noted from Figure 1 that the partition 7 stops short of thefront wheel 4 a slight distance and thus provides a slot. A flap orclosure plate 11 is hingedly carried by the front marginal wall 6 of thetop and is adapted to slide into this slot and to close the opening 9 inthe front wall 4 and thus close the mouth of the horn. A pair of guidingstrips or posts 12 are positioned adjacent the lateral edges of thepartition 7 and form braces between the bottom 1 and such partition, asclearly shown in both iigures. These strips 12 or posts form guidesagainst which the flap 11 slides. Preferably, the upper front portionsof the guides 12 are yslightly tapered to facilitate the removal of theflap 11, as may be seen from Figure 1. It desired, the top 5 may beprovided with a threaded pin 13 adapted to receive and store records 14,such records being held in place by means of a thumb nut 15.

In using the ldevice the top is opened andthe flap 11 is thus withdrawnfrom the mouth of the horn and hangs downwardly, as shown in Figure 2.Thereafter, the device is used in the usual manner without having anyobstruction for the horn.

It is apparent that if it is desired to lessen the volume of the soundemitted by the phonograph that any suitable plate may be slipped intothe slot between the partition 7 and the front wall 4 and may thusregulate the volume of the sound.

lhen the device is closed the mouth ot the device is completelyprotected and the horn is also closed, as shown in Figure 1, and thedevice may be carried by means ot the handle 16.

Although the invention has been described in considerable detail, it isto be under1 stood that the invention may be variously embodied and is,therefore, to be limited only as claimed.

I Claim:

1. A portable phonograph comprising a box like bottom portion having anupper horizontal partition, a record-'carrying disk positioned abovesaid bottom partition, a tone arm swivelly mounted adjacent a rearcorner of said partition and opening into said bottom portion, a hornCarried within said bottom portion and having a. deiiector plate carriedbelow said tone armsaid bottom portion having an open front walloommunicating with said horn, said partition stopping short of saidfront wall,`a cover hinged to said bottom portion and a Hap carried bysaid cover and adapted to slide between said partition and said frontwall to elose the aperture in said front wall.

2. VA portable phonograph comprising a box` like bottom portion havingan upper horizontal partition, a record-carrying disk positioned abovesaid horizontal partition, a tone arm swivelly mounted ad] aeent a rearCorner of said partition and opening into said bottom portion, a horncarried within said bottom portion, and having a deeetor plate carriedbelow'said tone arm, said bottom portion having an open front walloommunicating with said horn, said partition stopping short of saidfront wall, a cover hinged to said bottom portion and a {iap carried bysaid cover and adapted to slide between said partition and said frontwall to close the aperture in said 'front wall, said bottom portionhaving supporting posts positioned below the front edge of saidpartition adjacent its sides and forming guides for said Iflap.

In testimony that I claim the foregoing I have hereunto set my hand atMilwaukee, in the county of Milwaukee and State of Wisconsin.
